Answer:
metaphase I
Explanation:
This is where the genetics characteristics are exchanged in the chromosomes
Answer:
If the cancer cell's DNA is sequenced than the anticipated results will be that the cytosines in or close to the promoter region will get methylated. It has been stated that in the cancer cells one allele of p53 is mutated and the other allele, however, of exhibiting an intact promoter, does not express the protein.
Thus, it shows that the expression in the other allele gets suppressed by methylation rather than by mutation. Methylation generally takes place in CpG islands in or close to the promoter region and therefore inhibits transcription.

An example of a postzygotic mating barrier, low hybrid viability .
Hybrid offspring are born but have lower fitness and are therefore less likely to reach sexual maturity. Another example is where hybrid offspring is healthy but unable to breed.
Postzygotic mating barriers reduce the reproductive capacity of hybrid offspring. The three types of postzygotic barriers are hybrid zygote abnormality, hybrid infertility, and low hybrid viability . Many research theory suggests that incompatibility alleles those who have evolved neutrally are not able to be maintained in secondary contact.
